Current Attempt in Progress The speed of a car increases uniformly with time from 64 km/h at A to 110 km/h at B during 12 seconds. The radius of curvature of the hump at A is 41 m. If the magnitude of the total acceleration of the mass center of the car is the same at B as at A, compute the radius of curvature pp of the dip in the road at B. The mass center of the car is 0.63 m from the road. Assume PA = 41 m, h = 0.63 m. PB B Answer: PB= HI m
